Veriication of the implementation of the EPIA(s)
ISO 50015:2014(E)
3.6
energy
electricity, fuels, steam, heat, compressed air, and other like media
Note 1 to entry: For the purposes of this International Standard, energy refers to the various forms of energy,
including renewable, which can be purchased, stored, treated, used in equipment or in a process, or recovered.
Note 2 to entry: Energy can be deined as the capacity of a system to produce external activity or perform work.
[SOURCE: ISO 50001:2011, 3.5]
3.7
energy baseline
quantitative reference(s) providing a basis for comparison of energy performance (3.9)
Note 1 to entry: An energy baseline relects a speciied period of time.
Note 2 to entry: An energy baseline can be normalized for relevant variables (3.18) which affect energy use (3.12)
and/or energy consumption (3.8), e.g. production level, degree days (outdoor temperature), etc.
Note 3 to entry: The energy baseline is also used for calculation of energy savings, as a reference before and after
implementation of energy performance improvement actions (3.5).
[SOURCE: ISO 50001:2011, 3.6]
3.8
energy consumption
quantity of energy (3.6) applied
[SOURCE: ISO 50001:2011, 3.7]
3.9
energy performance
measureable results related to energy eficiency, energy use (3.12) and energy consumption (3.8)
Note 1 to entry: In the context of energy management systems, results can be measured against the organization’s
(3.17) energy policy, objectives, targets and other energy performance requirements.
Note 2 to entry: Energy performance is one component of the performance of the energy management system.
[SOURCE: ISO 50001:2011, 3.12]
3.10
energy performance improvement
improvement in measurable results related to energy eficiency, energy use (3.12) or energy consumption
(3.8) compared to the energy baseline (3.7)
3.11
energy performance indicator
EnPI
quantitative value or measure of energy performance (3.9), as deined by the organization (3.17)
Note 1 to entry: EnPIs (3.11) could be expressed as a simple metric, ratio or a more complex model.
Note 2 to entry: For the purposes of this International Standard, a quantitative value or measure of energy
performance developed by the M&V practitioner (3.15) is referred to as an energy performance metric.
[SOURCE: ISO 50001:2011, 3.13, modiied – Added Note 2 to entry.]
3.12
energy use
manner or kind of application of energy (3.6)
